In situations where a very large demand of hot water is required Rinnai Buffer Packs offer a cost effective solution. Using a manifold arrangement of either internal or external Rinnai Heavy Duty Condensing water heaters and a stainless steel buffer vessel, demands in excess of 20,000 litres per hour can be satisfied. Rinnai's stainless steel buffer vessels do not require electric immersion heating elements. The manifold system offers the additional benefit of operational cover should a water heater fail; easy access and isolation of a unit for servicing. Rinnai are proud to have been associated with very large prestigious water heating projects worldwide.
